Is there a protocol for looking for life in an environment like Enceladus that would sufficiently guarantee sterility of the probe?

It seems that guaranteeing sterility would be sufficiently impossible to render Enceladus permanently unapproachable.

There's a job at NASA for that. It's called the Planetary Protection Office: https://planetaryprotection.nasa.gov (relevant xkcd what-if: https://what-if.xkcd.com/117/)

I don't think you can guarantee the sterility of an object.

You can make it likely though.
